に溜まる水垢の量を減少させることができる。Since the cooling water pipe 25 of the casting pin 17 is composed of a stepped pipe integrally formed, it is easier to manufacture than the conventional cooling water pipe constituted by brazing a plurality of pipes having different diameters. Processing man-hours are greatly reduced. Moreover, the concentricity of the first to third segments 25 3 to 25 5 is more accurately ensured than that of the brazing cooling water pipe, so that the gap of the cooling water passage 26 (that is, the inner peripheral surface of the blind hole 24 and The gaps α, β, γ) with the outer peripheral surface of the cooling water pipe 25 can be kept constant, so that the flow rate of the cooling water can be stabilized and the cooling effect can be enhanced, and the cooling water can be contained in the cooling water. It is possible to prevent clogging of the cooling water passage 26 due to foreign matter. Further, since the step portions 25 1 and 25 2 of the cooling water pipe 25 can be formed smoothly as compared with the case of brazing, the step portions 25 1 and 25 2
It is possible to reduce the amount of scale accumulated in.
